Detailed Description

template<class T>
class RWMathVecIterator< T >

Class RWMathVecIterator is the random access iterator for the RWMathVec collection class. The RWMathVecIterator class behaves like a pointer to type T and is used to increment through elements of an RWMathVec.

Note

This class should be accessed through RWMathVec::iterator.

Example

#include <rw/math/mathvec.h>
 
int main() {
  RWMathVec<int> V(5, rwUninitialized);
  RWMathVec<int>::iterator i = V.begin();
  RWMathVec<int>::iterator stop = V.end();
 
  // Assign a unique int value to each element of V
  for (int j = 0; i != stop; ++i, ++j) {
    *i = j;
  }
}

Constructor & Destructor Documentation

RWMathVecIterator() [1/2]

template<class T >

RWMathVecIterator< T >::RWMathVecIterator ( )

inline

Constructs an RWMathVecIterator that is in an uninitialized state. The iterator must be initialized before it is dereferenced.

RWMathVecIterator() [2/2]

template<class T >

RWMathVecIterator< T >::RWMathVecIterator ( const RWMathVecIterator< T > & x )

inline

Constructs an RWMathVecIterator from another RWMathVecIterator. Initialized iterators can be obtained via the RWMathVec::begin() and RWMathVec::end() member functions.

Member Function Documentation

operator*()

template<class T >

value_type & RWMathVecIterator< T >::operator* ( ) const

inline

Returns a reference to the element pointed to by self.

operator++() [1/2]

template<class T >

RWMathVecIterator< T > & RWMathVecIterator< T >::operator++ ( )

inline

Prefix or postfix increment or decrement operator. The RWMathVecIterator points to the next or previous element in the RWMathVec. No error condition is set if the RWMathVecIterator goes past the bounds of the vector. Compare to RWMathVec::begin() and RWMathVec::end() to check that the iterator position is valid.

operator++() [2/2]

template<class T >

RWMathVecIterator< T > RWMathVecIterator< T >::operator++ ( int )

inline

Prefix or postfix increment or decrement operator. The RWMathVecIterator points to the next or previous element in the RWMathVec. No error condition is set if the RWMathVecIterator goes past the bounds of the vector. Compare to RWMathVec::begin() and RWMathVec::end() to check that the iterator position is valid.

operator+=()

template<class T >

RWMathVecIterator< T > & RWMathVecIterator< T >::operator+= ( difference_type d )

inline

Moves the iterator forward or backward d elements in the RWMathVec. No error condition is set if the iterator goes past the bounds of the vector. Incrementing by d and then decrementing by d returns the iterator to its original position, even if doing so takes it past the bounds of the vector.

operator-() [1/2]

template<class T >

difference_type RWMathVecIterator< T >::operator- ( const RWMathVecIteratorBase< T > & i ) const

inline

If the return value is positive, moves the iterator that many elements past the iterator i. If the return value is negative, moves the iterator that many elements before the iterator i.

operator-() [2/2]

template<class T >

RWMathVecIterator< T > RWMathVecIterator< T >::operator- ( difference_type d ) const

inline

Returns an iterator that is d elements past (or before) self.

operator--() [1/2]

template<class T >

RWMathVecIterator< T > & RWMathVecIterator< T >::operator-- ( )

inline

Prefix or postfix increment or decrement operator. The RWMathVecIterator points to the next or previous element in the RWMathVec. No error condition is set if the RWMathVecIterator goes past the bounds of the vector. Compare to RWMathVec::begin() and RWMathVec::end() to check that the iterator position is valid.

operator--() [2/2]

template<class T >

RWMathVecIterator< T > RWMathVecIterator< T >::operator-- ( int )

inline

Prefix or postfix increment or decrement operator. The RWMathVecIterator points to the next or previous element in the RWMathVec. No error condition is set if the RWMathVecIterator goes past the bounds of the vector. Compare to RWMathVec::begin() and RWMathVec::end() to check that the iterator position is valid.

operator->()

template<class T >

pointer RWMathVecIterator< T >::operator-> ( ) const

inline

For iterator a, and identifier m, a->m is equivalent to (*a).m.

operator=()

template<class T >

RWMathVecIterator & RWMathVecIterator< T >::operator= ( const RWMathVecIterator< T > & x )

inline

Replaces the current iterator position with x. Initialized iterators can be obtained via the RWMathVec::begin() and RWMathVec::end() member functions.

operator[]()

template<class T >

value_type & RWMathVecIterator< T >::operator[] ( difference_type n ) const

inline

Returns a reference to the element n elements after self if n is positive, or n elements before self if n is negative.
